The following observations are of course my personal view and do not claim to be the “truth”!
Here comes Ri Myong Sun (Korea):
Strengths:
very good footwork
consistent backhand and forehand chopping
backhand pimples seem to generate heavy backspin on loaded topspins
good and consistent forehand topspin though not often very fast
very good forehand smash
very good backhand serves with a lot of varieties
nice changing of sides when placing pushes and chops making the opponent move round the table all the time.
Weaknesses:
forehand chop occasionally going up too high
forehand chop is choppy always, so very predictable
she tends to push with the backup also too much from the forehand side such preventing herself from using forehand topspins or smashes to put pressure on the opponent
not using the pimples very often to block and flip a push ball in order to break the rhythm of the attacker.
Suggestions:
get greater variety of forehand serves
try to get in with forehand topspins a little faster trying to win the point directy
absolutely try to use the long pimples on the forehand when confronted with slow and spinny forehand topspins
practice awkward flips/lifts with the pimples when attacker pushes ball back too often.
practice counterspinning slow topspins into her forehand ideally with a lot of sidespin in order to break rhythm of attacker.
practice “float” defending with forehand making the attacker unsure whether the chop that comes back has much or no backspin at all.
